While in the foregoing is shown and described a preferred embodiment ofmy inven- 5 tion, I do not wish to be limited to the specific featuresof construction, combination, and arrangement of parts, as it isrecognized that many alterations such as adapting the device for use incooking stoves may be resorted to without departing from the spirit andscope of the invention as defined in the appended claim.

I claim: The combination with a liquid fuel stove having a burner, ahousing surrounding the burner and an annular seat on the housing, ofachimney comprising a cylinder of transparent. non corrosive materialseated on the annular seat and completely encircling the 2( burner, ametallic cylinder supported on the upper end of the first mentionedcylinder, 7 said metallic cylinder having a notch in its lower edge, alug adjacent the upper end of the non-corrosive cylinder for engaging inthe 5 notch to prevent rotation of one cylinder relative to the other,aplate closing the upper end of the metallic cylinder and tie rodsextending between the housing and the plate for holding the separateparts of the chimney tom gether and in position on the stove.
